This is a 092-0225FR+200 25.4 mm Dia. N-BK7 Enhanced Silver Plano-Convex Spherical Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a base shape of a circle with a diameter of 25.4 mm and a thickness at the center of 6 mm.
The mirror's geometry is spherical, with a radius of curvature (R1) of 200 mm, which results in an effective focal length (EFL) of 100 mm. This specific mirror is designed for use within the wavelength range of 600-1100 nm.
The mirror's substrate is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The front surface of the mirror is coated with EKSMA's enhanced silver coating, denoted as 'eks enhsil600110045'. This coating provides high reflectivity across the specified wavelength range.
